    Area of Science:

    • Oncology
    • Endocrinology
    • Molecular Biology

    Context:

    • Estrogen and progesterone receptor (ER/PR) status is a key biomarker in human breast cancer.
    • Accurate prediction of response to endocrine therapy is vital for patient management.
    • Recent advancements in non-steroidal antiestrogens have increased the importance of drug-based endocrine therapies.

    Purpose:

    • To highlight the predictive value of ER/PR measurements in human breast cancer.
    • To discuss the challenge of acquired hormone-independence during endocrine therapy.
    • To explore strategies for improving endocrine therapy efficacy.

    Summary:

    • Receptor measurement accurately predicts endocrine therapy response in 60-80% of responsive and 90% of unresponsive breast cancers.
    • Hormone-dependency can be lost during treatment, necessitating strategies to overcome resistance.
    • Combining chemotherapy with endocrine therapy or using adjuvant endocrine therapy may inhibit resistant cell proliferation.

    Impact:

    • Improved patient stratification for endocrine therapy selection.
    • Potential for novel combination treatment strategies to enhance breast cancer outcomes.
    • Enhanced understanding of endocrine resistance mechanisms in breast cancer.
